Enhanced CoRR-Beijing Normal University 3

CoRR (Consortium for Reliability and Reproducibility) is committed to building an open platform for sharing resources of brain imaging science, aiming to provide standardized benchmarking datasets for test-retest reliability and reproducibility assessment in functional and structural connectomics research. To achieve this goal, CoRR integrated multimodal magnetic resonance imaging (MRI) datasets from multiple laboratories worldwide in 2014, based on which:1. Establish test-retest reliability and reproducibility standards for commonly used connectivity measurments using MRI methods;2. Clarify the reliability fluctuation range of the above measurements in different imaging stations and retesting schemes;3. Build a standardized retest MRI dataset to serve the validation of new connectivity measurements. Since 2024, an enhanced version of CoRR has been updated to enhance the neuropsychometrics on brain imaging assessments. Through standardized image preprocessing processes and the psychometric design expanded from a single retest to to 9 retests, and the raw MRI datasets have been aligned to a standard brain spaces. In addition, all preprocessed brain imaging data is open to the public through the Science Data Bank, providing standardized and unified data support and technical references. We believe that this open science practice will largely foster the transdisciplinary research of human neuroscience. These data include 48 healthy controls from a community (student) sample from Beijing Normal University in China. Each participant has 3 resting state fMRI scans. During the first scan participants were instructed to rest with their eyes closed. The second and third resting state scan were randomized between resting with eyes open versus eyes closed.

可靠性与可重复性联盟（Consortium for Reliability and Reproducibility, CoRR）致力于搭建脑成像科学资源共享开放平台，旨在为功能连接组学与结构连接组学研究中的重测信度与可重复性评估提供标准化基准数据集。
为实现该目标，该联盟于2014年整合了全球多实验室的多模态磁共振成像（magnetic resonance imaging, MRI）数据集，并基于此开展三项核心工作：1. 建立基于MRI技术的常用连接组测量指标的重测信度与可重复性标准；2. 明确上述测量指标在不同成像站点及重测方案下的信度波动范围；3. 构建标准化重测MRI数据集，用于新型连接组测量方法的验证。
自2024年起，该联盟推出了增强版CoRR平台，以强化脑成像评估中的神经心理测量维度。该版本通过标准化图像预处理流程、将重测设计从单次扩展至多至9次的心理测量学方案，并将原始MRI数据集配准至标准脑空间。此外，所有预处理后的脑成像数据均通过科学数据银行（Science Data Bank）对外开放，为相关研究提供标准化统一的数据支撑与技术参考。
我们坚信，这一开放科学实践将有力推动人类神经科学的跨学科研究。
本次数据集包含来自中国北京师范大学社区（学生）样本的48名健康对照受试者。每名受试者均接受3次静息态功能磁共振成像（functional magnetic resonance imaging, fMRI）扫描：首次扫描时要求受试者闭眼静息；第二次与第三次扫描则在睁眼静息与闭眼静息两种条件下随机分配进行。
